MACHINE FOR OPEBAT ING UPON SOLES.

Patented Nov. *7, 1911.

- Application filed Kay 14, 1909. Serial No.-49o,051.

To all whom it m concern:

Be it known that I, FREDERICK M. FURBER, a citizen of the United States,residing at Revere, in the county of Suffolk and State of Massachusetts,have invented certain Improvements in Machines for Operating upon Soles,of which the following description, in connection with the accompanyingdrawings, is a specification, like reference characters on the drawingsindicating like parts in the several figures.

This invention relates to machines for operating upon 'soles and isshown embodied in a channeling machine. 7

The primary object of the invention is to provide an improved form offeeding mechanism of the type of that covered by an application for U..S. Letters Patent filed September 28, 1908, by Henry W. Winter, Ser. No.455,113. It will be understood that the feeding'mechanism hereinillustrated may be advantageously used upon any machine wherein .a soleis advanced against an operating tool by mechanism which engagesprlogressively the marginal portion of the so e.

In the prior application above referred to is shown a feed wheelcomprising a plurality of peripherally toothed sections arv along acurved line.

ranged for relative movement under the actionof a sole to accommodateswinging movement of the sole required in operating This priorconstruction is such that free forward movement of some or all of thefeed wheel sections is ermitted, but rearward movement thereof isprevented by mechanism transmitting movement vto the sections from adriving shaft. I have discovered that by arran in the independentlymovable sections for Eotfi free forward movement and free rearwardmovement between predetermined. limits such relative movement of thesections is permitted as may be desired to accommo ate swinging movementof the sole, and at the same time the sole is advanced against theoperating tool without, being mutilated along the surface engaged by thefree wheel. In the use of the present embodiment of the invention theinnerv feed wheel sections adjacent the edge of the sole are movedforwardly different amounts by the sole in swinging the sole, forexample, in going about the toe, as occurs in the use of the mechanismshown in said prior application. According to the present invention,however, after the toe portion has been finished and the machine reachesthe substantially straight portion at the side of the sole the forwardmovement of the sole is at first effected by the outer section orsections. The lost motion which must be takenup by the inner sectionsbefore they exert any feeding action is taken up withoutobjectionablemutilation of the sole caused by slipping of the outersections upon the sole. Such relative movement in the line of feedbetween the work and outer sections as occurs while the inner sectionsare taking up the lost motion is evidenced merely by slightly longerindentations made in the sole by the outer sections. In this way thelost motion referred to is gradually taken up and the forward movementof the s'ole is effected by an increasing number of sections until allof the sections come into action.

While it would be within the present invention to arrange all of thefeeding sections for free movement independently of each other withinsubstantially the same limits, I prefer to so construct the feedingmechanism that the independent movement of ,the respective sections isrestricted to amounts increasing-progressively from the outer sectiontoward the inner section. In the construction shown, the outer sectionhas no free movement under the action of the work so that at all timesit acts as a positive work advancing member. If all of the feedingsections were arranged for free forward movement in removing a sole fromthe machine, the withdrawal of the sole would advance some or all of thesections to the limit of their forward movement. This would necessitatea preliminary movement of the feeding mechanism in operating upon thenext sole before the lost motion occasioned by the withdrawal of theprevious sole would be taken up. By limiting the free movement of theouter section to a also illustrated herein yielding means for returningthe sections ,tofdrivapg position after the withdrawal of the sole.

' Other features of the invention will be hereinafter described.

i As will he apparent, in swinglng the section 14 is jmoved forwardlyupon the shaft 6 a greater amount than eithe'r' of the sections 8 and10. Similarly th fsecti on 12 is moved ahead upon, theshaft 6a; greateramount than the section 10. ,Sijrieel tlie section 8 is fixed upon theshaftitserve s to advance the sole while the remaining sections aremoved forwardly upon the shaft 6. hen the curved portion of the path ofoperation of the machine is completed and thesubstzmiially straightportion atthe side of the sole is reached, the forward movcment of thesole is. at first effected by the outer-section 8. It will be apparentthat the indentations formed inthe sole by the section 8 undenthesecircumstances will be longer than those produced by the, momentarilyidle sections 10 12 and 14. This permits the section 10 quickly to takeup its lost motion and assist the section 8 in advancing thesole'against the operating tool. It will be observed from Fig.2 that theteeth of the feed wheel sections are'angularly arranged andprojectforwardly; This feature may facilitate the takingup of the lost motionby the freely movable sections. In the manner thus described the severalsections of the wheel successively come into action until all of themassuinetheir operative positions upon the shaft (3.

. As is above pointed out, the spring 22 may be provided, if desired, toreturn the freely movable feed wheel sections to their operativepositions. This spring, however, may be omitted without departing fromthe present invention. The arrangement according to which the outer-feedwheel section isfixed upon the shaft and also the arrangement accordingto which the sections 10,. 12 and 14- are permitted different amounts ofmovement upon their shafts possess an advantage similar to that of thespring '22 inasmuch as they tend to reduce the forward movement of thesections movement thereof, and means for returning casioned inwithdrawing a sole from the mathe sections to the rearward limit oftheir chine. movement upon the withdrawal of the sole 50 Variations inthe construction shown may from the machine. be made without departingfrom the present 5.
